I took a seat at the kitchen table. I kept my face neutral, trying to act as if I wasn't sucking in every detail of the crime scene activity. I was frankly relieved to be out of sight of Ori, who was beached in death like an old sea lion washed up on the sand. She couldn't even be cold yet, but her skin was already suffused with the bleached, mottled look of decay. In the absence of life, the body seems to deteriorate before your very eyes. An illusion, of course – perhaps the same optical trickery that makes the dead appear to breathe.

Ann must have told them about injecting the insulin, because an evidence technician came into the kitchen within minutes and removed the vial of insulin, which he bagged and labeled. Unless the local labs were a lot more sophisticated than usual in a town this size, the insulin, plus all the samples of Ori's blood, urine, gastric content, bile, and viscera would probably be shipped off to the state crime lab in Sacramento for analysis. Cause of death was almost certainly anaphylactic shock. The question was, what had triggered it? Surely not the insulin after all these years – unless somebody'd tampered with the vial, a not unreasonable guess. Death might have been accidental, but I doubted it.

I looked over to the back door, where the thumb latch on the lock had been turned to the open position. From what I'd seen, the motel office was seldom secured. Windows were left open, doors unlocked. When I thought back to all the people who'd been trooping through the place, it seemed clear that anybody could have sauntered over to the refrigerator for a peek. Ori's diabetes was common knowledge, and her insulin dependency was the perfect means of delivering a fatal dose of who-knew-what. Ann's administering the injection would only add guilt to her grief, a cruel postscript. I was curious as to what Detective Quintana was going to make of it.

As if on cue, he ambled into the kitchen and took a seat at the table across from me. I wasn't looking forward to a chat with him. Like many cops, he took up more than his share of psychological space. Being with him was like being in a crowded elevator, stuck between floors. Not an experience you seek out.

"Let's hear how you tell it," he said.
